提高秋甘兰结球率是实现高产稳产的关键措施。有的秋甘兰结球率只有80—85%,严重影响产量。秋甘兰结球率降低的主要原因是:1.品种不良,在生产甘兰种子过程中,没有严格坚持选优去劣,降低选种标准。这样,经过多代繁殖,品种退化混杂,结球率便明显降低,所结的叶球形状也不一致,充实度也较差。
Increasing the rate of catching the ball in autumn is the key measure to achieve high and stable yield. Some of the autumn rate of only 80-85% turnout, serious impact on output. The main reasons for the decrease of the ball rate in autumn are as follows: 1. The varieties are not good. During the process of production of cabbage seed, there is no strict adherence to the selection of superiority and inferior selection criteria. In this way, after many generations of breeding, varieties of hybrid degradation, the ball rate will be significantly reduced, the shape of the resulting leaf ball is inconsistent, the degree of fullness is also poor.
